When I execute runlevel it returns "3 5" - could it be possible I'm running both?

Looks like only 14M diff.
runlevel 3 kills samba, mysql and httpd also. I would think that would be worth a little also.

I would be interested in changing runlevel 3 to start samba, mysql, and httpd. These are the ones I use all day.
This has been most informative and interesting!
Thnaks for your
help,

Note, at runlevels 123, the console will have a CLI login prompt, so you can
still log in there (and telinit 5) and switch virtual terminals
(ctl-alt-f2, etc). You just won't have the GUI (X) until you are at run level 5.
I don't know how much resources you'll free by doing this, as any processes
running would be idle. I suppose it'd free up some ram though. I'd be
interested to see the difference, if you'd care to compare and share your
results.
